Writes to PORTB are actually written to corresponding LATB register. Reads from PORTB register is
return of actual I/O pin values.
When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to
allow external control of the voltage on the pin.
Unimplemented: Read as ‘0’
ANSB<5:0>: Analog Select between Analog or Digital Function on Pins RB<5:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input
TRISB<7:0>: PORTB Tri-State Control bit
1 = PORTB pin configured as an input (tri-stated)
0 = PORTB pin configured as an output
LATB<7:0>: PORTB Output Latch Value bits
